Felt like using my BitPay card today...
To show how easily crypto is accessible nowadays and answer some questions to people that have a hard time calling this "real life".

This was my lunch...

I know, not fancy lunch, but I had little time to eat.

Here is the transaction:

How did I do?

Assuming you already have the BitPay Card (like the one I show here), and the BitPay app/account, it's quite simple:

Go to your phone app and load up your card with any BTC amount you wish (up to the limits, which I think to be 10k USD, but double check that on BitPay website). It will take current BTC price to convert BTC->USD. The load up process requires you to choose Normal Bitcoin Fees, which might (in some occasions) be a bit high. This will soon improve after 1 August (hopefully).
After the transaction verifying (1 confirmation only), you will be able to spend the amount you loaded into your card. That amount will show instantaneously at your card, but I feel it will be more secure if you wait for at least 1 verification (2-5 minutes usually).
Using the PIN code, I have did a debit VISA transaction at my workplace to buy a 3.5 NZD sandwich. That costed me, 2.59 USD plus 3% (0.07 USD) for converting USD to NZD.
